Hi Laura B:
Can your dog have sweet potato? I have been looking at fish based kibble that use smaller species fish and there are a few that use sweet potato as the carb. There is one I found that is potato free, but the calcium/phosphorous ratio is high and the nutrient levels are low. After reading comments about the company on DFA I decided to pass on it.
I read your comment about different proteins, you might want to consider trying a protein that your dog has not had before. I believe rotational feeding is healthier, but more importantly your dog will always have something he can do well on if/when a company changes or discontinues a food.
